View online: https://drupal.org/node/2103187

  * Advisory ID: DRUPAL-SA-CONTRIB-2013-078
  * Project: Quick Tabs [1] (third-party module)
  * Version: 6.x, 7.x
  * Date: 2013-October-02
  * Security risk: Moderately critical [2]
  * Exploitable from: Remote
  * Vulnerability: Access bypass

-------- DESCRIPTION  
---------------------------------------------------------

The Quick Tabs module allows you to create blocks of tabbed content,
specifically views, blocks, nodes and other quicktabs. You can create a block
on your site containing multiple tabs with corresponding content.

The module does not sufficiently check block permissions before rendering a
Quick Tab. Before this vulnerability was addressed, if a block had been
restricted to only appear for certain roles, that access was not checked
before rending it within a Quick Tab - leaving the contents of that block
visible to the world.

This vulnerability is mitigated by the fact that node and view permissions
are respected, meaning the vulnerability primarily exists for custom blocks
created for specific roles.
